To all whom t may concern.' Y

Be it known that I, BENJAMIN F. BLAKE- MAN, a citizen of the UnitedStates, residing atGreensboro, in the' county of Guilford' and Stat-e ofNorth Carolina, have invented a new and useful .(opylio'lclei,Y of whichthe following is a specification;

This invention relates to a oopyholder for use by' stenographers,typists' and the like.

' .The invention hasten its objects topfovid'ela c'opyhojlder wl'ii'ch;be" simple in its `oonstruction and operation and. oo nl- 'paratively'inexpensive; which' will kjleed copy of any length or Width, 'eitherthick or thin, such as copy-tissue or cardboards in whichvariable'spacing may be effected without any' adjustment, andv in whichcopy may be inserted or rei'novefd with a minimum amount of time andtrouble y The detailed construction ofthe invention together with Litsobjects and' advantages will be more fully explained in'y connectionwit-h `the accompanying 'drawings which illustrate the preferred form ofthe invention.

eferring in de Il to the drawings', the

f invention comprises a U-Ishaped. frame .10,-k

hwllgwen '.UPPQY ihOl-.Zolta'lg .111: ed a '1Q-Wert horiwifal les :12Athe @lidi 0fv #li lat-tiel bein-g secu-red in a metalfbloclr. 13"y atthe rear. end ofl a `housing 141., Rubber' cushions or sleeves 15surround the leg l2, and are adapte'dto rest on. a desk or table. pre-55. ferred to secure the'` end ofi the Vleg 12 in the block 1.3y by'means of a set' screw 16,361?" the is a vertical section through thelike, so that the frame k10 may be adjusted at any desired angle.

VThe 'upper legl'l of the U-shaped frame is formed with Ya'return bend17011 which a roller or platen 18 isrotatably mounted. A springy'Ii-'ietal plate 19 is secured at its lower-end tothel leg' 12, and atits upper end 1s pro-vided with afo'rward-ly projecting Sfeiv-'tl-irdedpi 20, Orl which isinounted a line guide 2l, adapted to bear agains'ttheroller 18. The line guide is nfriotionally lheld in positionfbyj` `atliinib screw 22, lwhich also serves to hold a linger', which normallyprojects upwardly above the roller andy pre- Vents the copyfrom bendingforwardly as 'it is' advanced Aup'vmdl-y over the roller.

The rollerflS covered 'with soft-rubber, andthe friction between thesaine and the paper A1s so much greater thanjthe friction 'between the'paper and the line gli-ide 21,

that there is no slippage between the copy and the roller. The rollerhas heads vrEiland secured in its ends which are,rotatably mounted on,theV return portion 17 of the v.upper leg of 'the frame, and thehead 25is formed with' a pulley 263, which is adapted to be actuatedby means ofva suitable belt 271 or thelike, to Arotate the roller.

f-TlIe belt 27 passes from the pulley 2G downwardly through a recess 2.8formed at Vthe rear endV of the housing' la and beneath idler' pulleys29 which' are 'rotatably mounted on a'spacer sleeveY 30 secured betweenthe sides of the housing. From ythe pulley 29 the "belt extends to v,theforward end of the housingV 14 and about a thumb wheel or pulley 31,which is rotatably mounted on afspacin'g sleeve '32 secured between thesides ofthe housing at the front end.' The housing is cut` awaya-s at 33suiciently so that the ,thumb orvnger may .engage the pulley- 31 torotate the samef Slots 34 are' cut in the front end of the housing' toprovide lingers 35 about whic'li may be secured a rubbercushion 8'6 forsupporting the front end ofthe housing'. A spacer 37 may be -seeuredbetween fingers 35 te prevent `the latter fronifbe'ng bent inwardly. p

The` eopyueldr isjsupprted mainly by the rubber sleevies lgand it isbraced 'bythe housingllc, which also-serves' to" prevent anyv thing fromgetting' caught in the beltV 27. The copyholder' is' so shaped that .theU- sha-Sped frame 1'0. may rest `o`n a kdesk behind [the typewriter',aan@ @hehe-using 14 extends.

fil

fmfwardly at the side of the typewriter, and the thumb wheel or pulley3l within easy reach. The copy may be placed on the roller i8 by simplybending the spring plate lll for "ardly by means of the thumb screw orlfnob l. rllie spring plate may be pulled for ardly to permit the copyto be straighteneaV or the line guide, which is frictionally held may beturned about the pin 2O an axis to follow the line. i

When the first line has been copied, the operator pushes the upper edgeof the thumb wheel for fardly until the next line is in position. Theextent of movement of the copy is `governed by the amount of move mentof the thumb wheel; a short push moves the Copy a small distance, and alonger push moves the copy a correspondingly greater distance, 'lhe copymaybe moved lnielwardly by pulling on the thumb wheel instead ofpushinf. The thumb engages the belt as well as the thumb wheel, so thatslippage of the belt on the wheel is prevented.

Thile the roller 18 will feed cards in the same manne as other copy, itis preferred to provide an attachment whereby a pile of cards may besupported and removed one at a time as they are copied. This attachment,as shown in Figures 7 and 8, consists of a backing plate 38, having astrip 39 secured to its rear face near the lower edge thereof,

`and adapted to rest on the upper surface of the roller with its rearportion extending beneath the leg ll. The front portion of this strip 59extends forwardly beneath the lower edge of the plate 2l? to form ashelf 41 on which the lower edge of the card may rest. lvlheu thisattachment is used, the roller lS remains stationary, and the tinger 23may be turned lo one side out of the way of the attachment, as shown inFigure 8.

lVhile I have shown and described in detail the preferred form of theinvention, it obvious that various modifications may be uiade thereinwithout any material departure from the essential features of theinvention. Itis my purpose to include all such modifications within thescope of the appended claims.

l. In a eopyholder, the combination of` a U-shaped frame havingsubstantially parat lel legs arranged one above the other, a rollerrotatably mounted on the upper leg and having a frietional surface, aspring plate secured to and extending upwardly from the lower leg andbearing against the roller to hold the copy, a line guide carried at theupper end of the plate, and means for rotating the roller in eitherdirection to `move the copy up or down.

Q. In a eopyholder, the combination of a U-shaped frame havingsubstantially parallel legs arranged one above the other, a roll errotatably mounted on the upper leg and having' a frictional surface, aspring plate secured to the lower leg and bearing against the roller, aline guide carried by said plate adjacent the roller, said line guidebeing centrally pivoted for adjustment with respect to the plate in aplane tangent to the roller, means for frictionally holding the saidline guide in its adjusted position, and means for rotating the rollerin either direction to move the copy up or down.

3. In a copyholder, the combination of a frame adapted to rest on a deskand having substantially parallel upper and lower members, a rollerrotatably mounted on the upper member and having a frictional surface, aspring plate secured to and extending upwardly from the lower member andbearing against the roller to hold the copy theron, a line guide at theupper end of the spring plate, said line guide being centrally pivotedand frictionally held to the plate so that it may be adjusted to alineit with the lines of the copy with the latter in any position,` andmeans for rotating the roller in either direction to move the copy up ordown.

4i. In a copyholder, the combination of a frame adapted to rest on adesk and having substantially parallel upper and lower members, a rollerrotatably mounted on the up per member and having a frictional surface,a spring plate bearing against the roller to hold the copy, a housingsecured to and extending forwardly from the lower part of said frame andconstituting a brace for supporting the frame in upright position, andmeans extending longitudinally within the the housing and connected tothe roller for rotating the latter to move the copy up or down.

5. In a copyholder, the combination of a frame having substantiallyparallel upper and lower members, a roller rotatably mounted on theupper member and having a frictional. surface, a spring plate bearing'against the roller to hold the copy. a housing secured to and extendingforwardly from the lower part of said frame and constituting a brace forsupporting the frame in upright position, a thumb wheel mounted in thefront part of the housing, pulleys at the rear end of the housing, apulley secured to theend of the roller above the rear end of thehousing, and a belt connecting said pulleys and thumb wheel whereby thelatter may be rot-ated to rotate `the roller and move the copy up ordown. i

6, In a copyholder, the combination of a U-shaped frame havingsubstantially parallel legs arranged one above the other, a rollerrotatably mounted on the upper legY andvhaving a frictional surface, aspring plate bearing against the roller to hold the copy, a housingextending forwardly from-` the end 0f the lower leg of the frame andlill constituting a bracev for supporting said frame in uprightposition, said lower leg being adjustably connected with the housingsothat the U-Shaped frame is angularly adjustable forwardly or backwardly,and means extending longitudinally Within the housing and connected tothe roller for 1'0- tatng the latter to move the copy up o1 down.

In testimony that I claim the foregoing as my own, I have hereto alxedmy Signature.
